Does uv irradiation is a 'all or nothing' process in bacteria inactivation?
Best insight from top research papers
UV irradiation is not an "all or nothing" process in bacteria inactivation. Different UV technologies and wavelengths have varying effectiveness in inactivating bacteria. The KrCl* excimer lamp emitting at 222 nm was found to effectively inactivate bacteria with a UV dose of 10 mJ cm^-2 . UV-C LEDs emitting at shorter wavelengths of the UV-C spectrum were also effective in inactivating bacteria, with 90% inactivation rates achieved at mean UV-C doses of 1.7-1.9 mJ cm^-2 . UVGI using UVC (254 nm) and UVD (185 nm) sources resulted in inactivation efficiencies of 2.2 and 3.1 logarithmic order, respectively, at an exposure UV dose of 370 J/m^3 . Additionally, the use of UVA irradiation with photosensitizers such as vitamins and benzophenone enhanced the bactericidal effect, with over six logs CFU/ml reduction observed . Therefore, the effectiveness of UV irradiation in bacteria inactivation depends on the specific UV technology, wavelength, and exposure dose used.

What are the environmental implications of using UV technology as a food conservation method?5 answersThe environmental implications of utilizing UV technology for food preservation are significant. UV light treatment offers a non-thermal and non-chemical approach, aligning with the increasing consumer demand for natural and healthier food products without chemical preservatives. This technology not only helps in reducing product losses but also enhances nutritional quality, sensory properties, and antioxidant capacity of fruits and vegetables. UV treatment is environmentally friendly, as it does not require the addition of chemicals or heat, making it a promising and sustainable method for extending the shelf life of food products. However, improper application of UV treatment can lead to adverse effects such as changes in food composition, protein digestion, antioxidant damage, lipid oxidation, and loss of sensitive vitamins.
How does the use of UV light and silver ion affect the growth and survival of bacteria and viruses?5 answersThe use of UV light and silver ions has shown significant effects on the growth and survival of bacteria and viruses. UV light, particularly in the UVC range, has a potent microbicidal effect, impacting different microbial forms based on their susceptibility. Studies have demonstrated that UV exposure reduces bacterial abundance, affecting various phyla differently. Additionally, UV light exposure has been found to decrease the survival of pathogenic bacteria, such as Staphylococcus aureus and Streptococcus faecalis, leading to a significant decrease in colony-forming units. On the other hand, silver ions have also been effective in limiting microbial growth. The combination of UV light and silver ions in technologies like the ARIS-K2 robot has shown promising bactericidal action, reducing bacterial populations on surfaces effectively. These findings highlight the potential of UV light and silver ions in controlling the growth and survival of bacteria and viruses.
What is the role of UV radiation for plants?5 answersUV radiation plays a multifaceted role in plant growth and development. UV-A, UV-B, and UV-C radiation impact plants differently. UV-A, the main component in nature, can stimulate plant growth in controlled environments. UV-B, although damaging due to ozone depletion, can trigger various plant responses, affecting photosynthesis, growth, and productivity. UV radiation alters plant metabolism and development, affecting primary and secondary processes. Additionally, UV exposure can influence plant quality, growth, photomorphogenesis, and resistance to stressors, potentially enhancing biomass growth and the production of beneficial compounds. Postharvest UV irradiation is also utilized to preserve vegetables, delaying senescence, enhancing antioxidant activity, and improving nutritional quality. Overall, UV radiation plays a crucial role in plant responses, growth regulation, and the production of bioactive compounds.
What is the condition of inactivation of bacteria using UV-C?5 answersUV-C light is an effective method for inactivating bacteria. The inactivation rate of bacteria depends on factors such as the wavelength of the UV-C light and the radiation intensity. Studies have shown that UV-C light with wavelengths of 260 nm and 280 nm can effectively inactivate bacteria such as Escherichia coli and Staphylococcus aureus. The inactivation process follows a variable order kinetic, with the rate of inactivation changing over time. The effectiveness of UV-C light in inactivating bacteria can be enhanced by coupling it with UVA light, which has a shorter wavelength. The distance between the UV-C light source and the bacteria also affects the inactivation rate, with closer proximity resulting in higher inactivation rates. Overall, UV-C light has been shown to be a valuable tool for the inactivation of bacteria in various applications, including food contact surfaces and liquid foods.
Does power ultraosund is a 'all or nothing' process in bacteria inactivation?5 answersPower ultrasound is not an "all or nothing" process in bacterial inactivation. The efficacy of power ultrasound in bacterial inactivation depends on various factors such as ultrasound frequency, power level, treatment time, and the type of bacteria being targeted. Studies have shown that power ultrasound can effectively inactivate bacteria, including Escherichia coli, Listeria monocytogenes, Bacillus cereus, and Staphylococcus epidermidis, with inactivation rates of more than 99% achieved in some cases. The inactivation process is influenced by the generation of acoustic cavitation bubbles, which can cause mechanical damage to the bacterial cells and generate free radicals and hydrogen peroxide that contribute to the inactivation. The rate of inactivation increases with the increase in ultrasound power and decreases with the addition of radical scavengers to the bacterial suspension. Therefore, power ultrasound can effectively inactivate bacteria, but the extent of inactivation depends on various factors and is not a binary "all or nothing" process.
What is the effect of UV-powder on bacterial proliferation under home conditions?4 answersUV-powder has been found to be effective in reducing bacterial proliferation under home conditions. In a study conducted by Munoz-Price et al., commercially available UV powder was applied weekly to high-risk objects within patient rooms, resulting in a significant increase in cleaning rates from 41.8% to 80%. This suggests that the use of UV powder can effectively inhibit bacterial growth and improve cleanliness in home environments.
